The purpose of this study is to verify the mediating effect of empowerment on the relation between job characteristics and creativity. This study also examines the relationship job characteristics and creativity. As a result of this study, job characteristics had positive influence on empowerment. Empowerment had positive influence on creativity. Also job characteristics had positive effect on creativity at first, but it did not have a direct effect on creativity when empowerment was considered. These mean that empowerment is complete mediation variable because job characteristics no longer affects creativity after empowerment has been considered. Several implications, limitations and directions for future research were discussed.

The purpose of this study is to verify not only the impact of servant leadership affecting creativity but the mediating effect of empowerment. Creativity refers to the production of novel and useful ideas by an individual or by a group of individuals working together [2]. A survey was conducted by 301 employees. This study used the structure equation model which treated the servant leadership as independent variable and creativity as criterion variables. Empowerment was supposed as mediating variable of these relationships. As a result of this study, servant leadership had positive influence on empowerment. Empowerment had positive influence on creativity. Also servant leadership had positive effect on creativity at first, but it did not have a direct effect on creativity when empowerment was considered. These mean that empowerment is complete mediation variable because servant leadership no longer affects creativity after empowerment has been considered. Several implications, limitations and directions for future research were discussed.

본 연구에서는 근전도 신호를 활용하여 정상인의 보행과 관련된 상지와 하지 근육의 신호를 확인하고 저항센서를 이용하여 정상적인 보행 패턴을 확인하였다. 대학생 15명을 대상으로 정지해 있을 때와 평지를 보행할 때, 상지의 4부위(대흉근과 승모근)와 하지의 10부위(대퇴직근, 대퇴이두근, 내측광근, 외측광근, 반막양근, 반건양근, 가자미근, 장비골근, 내비복근과 외비복근)에 전극을 부착하여 근전도를 측정하였다. 저항센서는 양측 발바닥의 8부위에 센서를 부착하여 보행시 발에 가해지는 압력을 측정하였다. 그 결과, 근전도 신호는 정지상태에 비하여 보행 시에 허벅지의 외측광근과 반건양근을 제외하고 모든 근육에서 유의하게 높은 진폭을 가졌다. 또한 보행주기의 두 단계인 입각기와 유각기와 관련된 근육을 확인하였다. 저항 센서의 신호 분석 결과, 평균 보폭 주기 동안 크게 입각기와 유각기의 두 주기와 세부적으로 여덟 단계-초기 접지기, 하중 반응기, 중간 입각기, 말기 입각기, 전 유각기, 초기 유각기, 중간 유각기, 말기 유각기-의 보행 주기를 확인할 수 있었다. The aim of this study was to investigate upper and lower limb muscle activity using EMG(electromyogram) sensors while walking and identify normal gait pattern using FSR(force sensing resistor) sensor. Fifteen college students participated in this study and their EMG and FSR signal were measured during stopping and walking trials. EMG signals from upper(pectoralis major and trapezius) and lower limbs(rectus femoris, biceps femoris, vastus medialis, vastus lateralis, semimembranosus, semitendinosus, soleus, peroneus longus, gastrocnemius medialis, and gastrocnemius lateralis) were obtained using the surface electrodes. FSR measured pressures on 8 areas of the sole of the foot during walking. EMG results showed that all muscle activities except for vastus lateralis and semimembranosus during walking had higher amplitudes than stopping. Additionally, muscle activities associated with stance and swing phase during walking were identified. Results on FSR showed that stance and swing phases were detected by FSR signals during a gait cycle. Eight gait phases-initial contact, loading response, mid stance, terminal stance, pre swing, initial swing, mid swing, and terminal swing- were classified.

The purpose of this project is to propose the public design development "C" university campus square using the formative characteristics of lines. The campus square design uses a motif of lines as geometric forms, which organically connects and weaves four elements : human, nature, space and culture. To materialize this concept, vertical and horizontal lines were employed to symbolize the images of university and emphasize the local traits, thus making this campus an urban attraction. There are two major spaces in the square design. The first is a culture street, the landmark street that is set up to reflect the axis of space. The second is green carpet, the community and cultural street that are used for various events and multi-purposed community square that is able to accomodate activities such as gathering and performance. The facility and material plans will be considered for the familiarization of human with nature, use of easily maintained facilities with durable materials, maximization of the effects of pubic relations using of university identity.

공포에 대한 연구는 주로 불안과 공포 장애를 가진 환자들을 대상으로 수행되어왔으며, 공포를 불안의 특수한 한 형태라고 생각하여 불안과 공포에 대한 연구가 함께 이루어져왔다. 본 연구에서는 아동이 공포 정서를 경험하는 동안 나타나는 자율신경계 반응을 밝히고자 하였다. 초등학생을 대상으로 공포 정서를 유발하는 시청각 동영상을 제시하고 심리 반응과 자율신경계 반응을 측정하였다. 연구 결과, 공포 정서의 적합성 및 효과성은 80%이상으로 나타나 공포정서유발자극이 적절하고 효과적이었음을 알 수 있었다. 자율신경계 반응 분석 결과, 공포정서가 유발되는 동안 피부전도수준, 피부전도반응, 피부전도반응의 수, 호흡주기관련 심박률 변화, 호흡수, 심박률분산의 고주파수 성분이 유의하게 증가하였고, 심장박동주기는 감소하였다. 공포 정서에 의해 야기된 자율신경계 반응에서는 불안수준이 높을수록 피부온도, 심박률, 호흡주기관련 심박률 변화가 큰 것으로 나타났다. 본 연구는 불안수준이 높은 아동일수록 공포 정서를 경험할 때 자율신경계 반응의 변화가 더 크다는 것을 나타낸다. There have been many studies on patients who suffer from anxiety disorders. However, there is been not enough attention on the difference in the level of between the two populations with and without anxiety disorders. This study was performed to investigate the difference in the ANS responses induced by fear in children. Experimental procedures were as follow: All subjects were in upper grade levels in elementary school. ANX(anxiety) scales of PIC(Personality Inventory for Children) were used to measure fear anxiety. Audio-visual clips were used as stimulus to provoke fear emotion. Baseline of physiological signals, ECG, PPG, EDA, and SKT, were measured for 30 seconds before the fear stimulus. Physiological signals were then recorded for 2 minutes while fear is evoked. Psychological and physiological responses were analyzed. All the children reacted to the fear stimulus with high intensity of fear. Physiological responses showed that SKT, SCR, NSCR, HR, RSA, RESP, HF were increased, while R-R was significantly decreased, respectively, during the period of fear induction. Analysis of the level of anxiety and the physiological responses produced by the experience of fear revealed a statistically significant positive correlation in SKT, HR, and RSA. In other words, the higher the level of anxiety, the higher the levels of SKT, HR, and RSA when children experienced fear. In conclusion, it is confirmed through this research that physiological responses to fear is associated with the level of anxiety each individual.

본 연구에서는 유머를 경험하는 동안 나타나는 아동의 안면근육반응을 확인하고 유머 정서에 의해 유발된 안면근육반응과 우울 수준과의 관계를 연구하였다. 실험에 앞서 또한 아동의 우울 수준을 측정하기 위하여 12∼13세의 아동 43명(남 22명)에게 한국판 PIC 검사의 우울 척도를 평가하도록 하였다. 실험이 시작되면, 자극이 제시되기 전 60초 동안 안정 상태를 측정한 후, 유머를 유발하는 시청각 동영상 자극을 제시하는 동안 안면근육반응(양측 추미근, 구륜근)을 측정하였다. 자극 제시가 끝나면 자신이 경험한 정서를 정서평가척도 상에 평가하도록 하였다. 아동의 95.3%(41명)이 유머를 경험하였다고 보고하였고 그 강도는 3.81(5점 만점)로 나타났다. 안면근육반응은 안정 상태에 비하여 유머 자극이 제시되었을 때 유의하게 증가하였다. 안면근육반응과 우울 수준과의 상관을 확인한 결과, 우측 추미근에서 유의한 부적 상관이 나타났다. 이는 우울 점수가 높은 아동일수록 유머를 경험할 때 안면근육을 적게 움직임을 의미한다. The study is to examine relationship between the level of depression and facial EMG responses during the humor condition. Forty-three children(age range 22-49 years) participated in the study. The Korean Personality Inventory for Children(KPI-C) was used to measure the level of depression in children. While children were presented to audio-visual film clip inducing humor, facial EMG were measured on their faces(bilateral corrugators and orbicularis). A baseline state was measured during 60 seconds before the presentation of the stimulus, i.e., emotional state lasting 120 seconds. Participants were asked to report the intensity of their experienced emotion. The results of emotion assessment showed 95.3% appropriateness and 3.81 intensity on the 5 points Likert scale). Facial EMG showed a significant increase while participants experiencing humor compared to baseline state. Additionally, the result showed a negative correlation between right corrugator responses and the level of depression. The study findings showed the more children experienced depression, the less facial EMG activity they had while experiencing humor.

However, unlike the past, current elderly people are required a high quality of life. Consequently, there has recently been a increasingly faster development of the welfare housing for the aged. Especially, since the elderly residents of elderly selfare housing are at an age range in which they experience decrease in social activities, there is a need for public spaces to support their health and everyday lives. Therefore this study aims to find out the planning characteristics of space organization of the public spaces in urban elderly welfare housing as to provide the basic materials for planning spaces for the elders.

청소년의 자해 경험에 대한 질적 사례 연구: 거기서 기다리는 나는 없다

장은혜 ( Jang Eun-hye ) 한국교육인류학회 2021 교육인류학연구 Vol.24 No.4

이 연구는 여자 고등학생 참여자의 자해 경험에 대해 질적 사례 연구로 이해하고자 함이 목적이다. 본 연구자는 참여자의 자해행동에 대한 의미를 중층적으로 살펴보고, 레비나스(Levinas)의 타자철학으로 낯설게 보기를 시도하였다. 자료수집은 반구조화 질문으로 10회기 심층 면담을 주(主)로 하였고, 자료의 다각화를 위해 현장 관찰과 현지 자료들을 참고하였다. 심층 면담을 통해서 범주화된 참여자의 자해 경험은 14개의 소범주, 7개의 중범주, 2개의 대범주이다. 중범주는 ‘집안에서 유능한 맏딸로 압박받기’, ‘학교에서 반 꼴찌 면하기 위해 발버둥치기’, ‘사회에서 완벽한 여자사람 되기’, ‘또래에게 외면당하기’, ‘자해의 시작’, ‘중독으로 빠져들기’, ‘벗어나기’로 주제화되었다. 참여자의 비자살적 자해행동은 초기에 스트레스 해소 역할을 했으며, 자살적 자해행동으로 이행했다가 극복과정에서 다시 비자살적 자해로 이행하였다. 참여자가 원하는 도움은 존재 대(對) 존재로서 만남의 관계였다. 본 연구자는 이 연구를 통하여 청소년 자해행동에 대한 이해와 함께 폭력과 소외, 윤리적 관계 맺음을 성찰하고 전체성으로 환원하는 우리 사회의 구조적인 문제에도 접근하고자 하였다. The purpose of this study is to understand the experiences of self-injury behavior of adolescent participants through qualitative case study. In order to understand the meaning of the participant’s self-injury behavior in layers, the researcher adopted the Levinas' philosophy to see it unfamiliarly. The study collected data mainly from the ten in-depth interviews with semi-structured questions with one female high school student. In addition to in-depth interviews, local data were referenced along with field observation for data diversification. Participant’s non-suicidal self-injury behavior initially played a role in relieving stress, transitioned into suicidal self-injury behavior, and then to non-suicidal self-injury behavior in the process of overcoming it. The participant of the study needed deep sympathy and the fulfilled relationship as ‘being to being,' The study provides an in-depth understanding of adolescent self-injury behavior and reflects on conducting counseling. Furthermore, it is intended to have the significance of the importance of qualitative nurturing and caring of adolescents in their growing phase with the ‘ethical relationship.’ Through this study, I tried to reflect on violence, alienation as well as approach the structural problem of our society in which the other is reduced to the totality.
